Matt Stone and Trey Parker — the “South Park” creators known for their take-no-prisoners mockery of cultural issues from both sides of the sociopolitical aisle — apparently are feeling a little guilty for mocking Al Gore’s climate change evangelism.

Gore was a month away from releasing “An Inconvenient Truth” when that episode came out — and the network noted that since ManBearPig was fictional, that suggested Stone and Parker were mocking climate change.

But in this week’s episode, “Time to Get Cereal,” ManBearPig turns up and kills several residents.

After they beg, an indignant Gore turns on them: “Oh, is it inconvenient now?

Gore finally relents — but only after he forces the kids to apologize: “Say you’re sorry for making fun of me.” They do, and the hunt for ManBearPig moves forward.
